The Vegetable Production System (Veggie) is a plant growth system developed and used by NASA in space environments. The purpose of Veggie is to provide a self-sufficient and sustainable food source for astronauts as well as a means of recreation and relaxation through therapeutic gardening. [ 2 ]
The study of plant response in space environments is another subject of astrobotany research. In space, plants encounter unique environmental stressors not found on Earth including microgravity, ionizing radiation, and oxidative stress. [23] Experiments have shown that these stressors cause genetic alterations in plant metabolism pathways.
Zinnia plant in bloom aboard an Earth orbiting space station. The growth of plants in outer space has elicited much scientific interest. [1] In the late 20th and early 21st century, plants were often taken into space in low Earth orbit to be grown in a weightless but pressurized controlled environment, sometimes called space gardens. [1]
However, plants experience normal growth given that directional light is provided. [10] Normal growth is classified as opposite root and shoot growth direction. This being said, many plants grown in a space flight environment have been significantly smaller than those grown on Earth's surface and grew at a slower rate. [10]
ISRU reverse water gas shift testbed (NASA KSC) ISRU Pilot Excavator – A NASA project. In space exploration, in situ resource utilization (ISRU) is the practice of collection, processing, storing and use of materials found or manufactured on other astronomical objects (the Moon, Mars, asteroids, etc.) that replace materials that would otherwise be brought from Earth.
In botany, a sport or bud sport, traditionally called lusus, [2] is a part of a plant that shows morphological differences from the rest of the plant. Sports may differ by foliage shape or color, flowers, fruit, or branch structure. The cause is generally thought to be chance genetic mutations [3] in a single cell.
In 1999, NASA allocated funding to support the development of an inflatable low-mass aeroponic system (AIS) for high-performance food production in both space and on Earth. [31] The AIS is a self-contained and self-supporting system designed to deliver nutrients and mist to plant roots in an aeroponic environment.
Space manufacturing or In-space manufacturing (ISM in short) is the fabrication, assembly or integration of tangible goods beyond Earth's atmosphere (or more generally, outside a planetary atmosphere), involving the transformation of raw or recycled materials into components, products, or infrastructure in space, [3] where the manufacturing ...
